Well, The choice of being a cracker or a hacker is of the person, so we can not be sure if he is a hacker or a cracker. A hacker would try to bring a hole in the os or a system to the open and try to work for a better / secure internet. Read ESR's definition of hacker here.

About RConnect is not secure, No internet connection is secure by default, I am against ISPs blocking your ports etc based on "security reasons". If one has to use internet, then he must learn to secure it too. Simply keeping a password would have prevented that (l)user's files from being accessed.
There are many firewalls freely available in the internet. If one doesnt have the time or patience to download and install one, its his negligence.
And to our Cracker, You can port scan, Entering to other;s systems is illegal in every part of the world. One simple advise, dont get busted, grow up.
